Thread: Problem passing a pointer

All I am trying to do here is change the first letter to a capital. While I'm in the function makefirstcapital the first letter is changed, the odd part comes when I go back to main firstname is bumped to secondname, and firstname has random stuff in it.

Code:

#include <iostream>
#include <stdlib.h>
#include <string.h>

void makefirstcapital(char*);
using namespace std;

int main(int argc, char *argv[])
{

  char first[20],second[20];
  cout<<"First name:";
  cin>>first;
  cout<<endl<<"Second name:";
  cin>>second;
  makefirstcapital(first);
  cout<<endl<<first;  



  
  cout<<endl;system("PAUSE");	
  return 0;
}
 

void makefirstcapital(char *name)
{
  char switchchar[1];

  switchchar[0]=name[0];
  strupr(switchchar);
  name[0]=switchchar[0];
}

Am I passing the pointer wrong? I appologize if this is a noobish question.
